usually in a big cloud there are many images and flavors,
while each given project might use only some of those.
This patch introduces '--name-lookup-one-by-one' argument to
server list command (mutually exclusive with '--no-name-lookup')
When provided (or either '--image' or '--flavor' is specified) to the
`server list` command, name resolving for
corresponding entity is now using targeted GET commands instead of
full entities list.
In some situations this can significantly speedup the execution of the
`server list` command by reducing the number of API requests performed.
